Arthur Clark believed himself the victim of gross injustice. His bicycle had brought him into disgrace. He had come home flushed with victory, ready to be hailed as the uncrowned king of scorchers, and here he was virtually a prisoner in his room, thither he had been sent directly after a wretched supper of oatmeal porridge.

"I wouldn't mind it if I had been ordered not to go into the road race," he said to himself, for the fiftieth time, as he rolled impatiently in his bed; "but just because I promised my father I wouldn't do any riding that would exhaust me, he has packed me off to bed as if I were a mere child. That's pretty rough on a fellow of fourteen. Anyhow, I beat all the scorchers in our school, and that's something."

Arthur could not go to sleep. He twisted and squirmed from one side of the bed to the other, listening to the solemn protests of the katydids and the shrill chirping of the crickets. That industrious prompter, conscience, began to annoy him shamelessly. Now that the first flush of his resentment had died away, he thought that perhaps his father was right after all. True, he had beaten all the other fellows easily; but then, what if it had been a hard struggle? Wouldn't it have exhausted him? It occurred to him that he had broken his word.

Arthur fell asleep very late. He usually slept so fast and so hard that from bedtime until the rising bell seemed like one minute. But now he tossed restlessly. His sleep was light. Suddenly he found himself sitting bolt-upright in bed. He saw a streak of pale whitish light on the floor and across his bed, and caught a glimpse of the moon. Oh, yes, it was the moon that had awakened him. Queer that had never happened before. He would go to sleep again. Then a rough, rather hoarse voice startled him. It came from his father's room.

"You're comin' right down ter de bank, dat's wat you're goin' ter do," the voice said, "an' if ye don't open de safe ye'll be learned how—see?"

"I shall not go one step. You may do your worst." It was his father's voice now.

"Hurrah for you, father!" Arthur could hardly keep from shouting. Then there was silence for a moment. He heard two sharp clicks that told of the cocking of a revolver; then his mother's voice pleading with his father to remember the children. Now there was the sound of a struggle. The burglar won, although he feared to use his revolver least the noise might summon help. Arthur understood it all. His father was the cashier of the Traders' Bank. The burglar probably had an accomplice outside who would help take his father to the bank and force him to open the safe.

Help must be got. The bank was in Plainfield, three miles away. If only there were some way of telephoning to the police station! He knew that a sergeant sat there all night. Men slept upstairs. But there was no telephone. Now a thought came to him that almost made him shout for joy. In ten seconds he had jumped into his sweater and knickerbockers, and was lacing on his rubber-soled bicycling shoes. He did not wait for a hat or stockings. He peered anxiously over the edge of the porch roof into the backyard. No, there was no one watching there. Noiselessly the boy lowered himself over the edge, and climbed down one of the pillars, crushing the honeysuckle vine as he went. He found his bicycle leaning against the house, where he had left it that afternoon after the race.

He picked up the wheel and walked on tiptoe across the grass at the rear of the house. He threaded his way between the rows of corn-stalks in the kitchen-garden. He made a long circuit, and at last came out in the road. Then he mounted his bicycle and wheeled away at a pace that would have astonished his friends. Going down hill he was very cautious. He back pedalled. There must be no falling; therefore no coasting. Again on the level road, he shot forward like a racer. He knew that if the burglars got his father into the bank they would try to make him open the safe in which $70,000 had been deposited that day. His father would resist, he knew. He remembered what had happened to other bank cashiers who resisted. The thought choked him. He bent over his handle bar, and the wheels seemed to fly. The pale, sinking moon, the silent road that stretched its white length before him, the tall trees, mysterious in their own dark shadows, the grass shining with dew, all made a picture that he never forgot. Above all, a scene stood out that he could not shut from his mind, try as he might—his father in the hands of the two ruffians, resolutely defying them in face of awful danger.

The sergeant nodding in his chair in the police station at one o'clock in the morning was startled by the vision of a bareheaded, white-faced boy.
